fraction is a part of a wholetelling you this from the depth of my souldon’t let this confuse your headall you need to know is what I just saidtop number is the number where we startcalled the numerator, this is the partdenominator is the number belowthis is the whole, am I goin’ to slowChorus:fraction is a part of a wholetelling you this from the depth of my soulgoing to use this even when you’re oldok now we’re on a rollfractions are easy to multiplylisten up now gonna tell you whyif you wanna do it just the right waythen you gotta listen to what I saymultiply the top called the numeratorsmultiply the bottom called the denominatorsdon’t forget to simplify when you’re done‘cuz multiplying fractions can be mad fundividing is more of the sameflip the second fraction, don’t be lamechange the operation to multiplynow you know what to do, don’t ask whyChorusat this next part you really gotta thinkfor adding fractions you’re gonna have to linkthe two together with a common denomadd the top only man ain’t this the bombsubtracting is pretty much the same wayas adding you heard what I saysubtract the top and remain calmas long as you found the common denomif your answer is an improper fractionyou’re not finished you gotta take some actionto a mixed number you gotta change backand simplify to lowest terms c’mon don’t slackChorusan improper fraction you know how to figurebottom is small and the top is biggerremember that the line means dividegotta do long division can’t let you slidewhat you got left is the numeratordivisor will be you denominatoradd it to the whole and now it’s all fixedsimplify, you got a number that’s mixednot sure how to simplifyfind a common multiple gonna tell you whyreduce that fraction to lowest termsbetter do this or else get burnedChorus

Chorus:take all the points equidistantfrom one center and in an instantyou have a shape that very familiara circle is round and well, it’s circularparts are real easy, a few you need to knowradius is length of center to outside, yodouble radius and you’ve got diametergoes from one side straight to the othertake the outside and go all the way aroundlength is circumference, like a king’s crowngo around a wheel, my bling, or anything that’s roundsee circumference everywhere, don’t be no clownspecial number you also need to know called πmathematical constant, same everywhere, whydivide circumference by diameter, this is pretty flyalways get 3.14 no matter circle’s sizeChorusEgyptians were the first to discover piused it to build the pyramids so hightallest manmade structures in the world, believe mefor nearly 4,000 years until 1311 A.D.let’s say circumference is C, diameter dthen C=πd, aint this easyif radius is r then C is 2πrSince d is double r, now we’re goin really farlet’s try an example with Dayton 22’s22 inches in diameter you useuse C=πd on that sweet ridelength around that rim is 69.115Choruswhat if you want to know the size of some blingdroppin a G per sq inch of that round thingneed to know the area to figure out the costA=πr^{2}, now you the bosstimes the radius by itself then piradius is 3 inches, 3^{2} is 9wastin your dollars, instead you could buy a carprice of that piece is more than 28 largewhen your ridin’ on your Ds and you got a mad thirstis a soda can enough, gotta know sumthin’ firstcan is a cylinder, top is a circle aightfind area then multiply by heightChorusfind volume of how much the can can fillit’s V=πr^{2}h, now you can chilluntil you get to the basketball gamesee that sphere get taken to the hole by LeBron Jamesrules say make C 29.5 inches dudecan you find the volume if it’s 4/3πr^{3}any circumference equals 2πrtold you this is true no matter where you aredivide each side by 2 and get 14.75then by π and r equals 4.695plug that in to 4/3πr^{3} fo shovolume in cubic inches is about 434
